Finding the Dimensions of a Rectangular Patio with Area Square Feet
Apply the geometry problem-solving strategy to find the dimensions of a rectangular patio when its area is square feet and the width is three feet less than the length. Let represent the length, making the width . Substitute these expressions into the area formula to get . Distribute to produce , and subtract from both sides to rearrange into the standard quadratic form . Factor the trinomial into . By the Zero Product Property, or . Since a physical length cannot be negative, discard . The length is feet, and the width is feet.
